Specification of Letters Patent.

Application filed J anuary 29, 1913. Seria1 No. 744,940.

To all whom, it may concern.

- Be it known that I, HENRY Orennon'rrr, a citizen of the United States, residing at Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented new and useful Improvements in Belt-Replacers, of which the following is a specification.

This invention relates to a belt repl'acer which is adapted to be used'in replacing belts upon the pulleys from which they have become disengaged, the primary object thereof being to provide a device of this character which will be very efficient in operation, which is very light and simple in construction so that it may be easily'operated and manufactured at a small cost, and which may be operated without danger to the operator.

The invention consists in the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of the device; Fig. 2 is a front. elevation thereof; Fig. 3 is a longitudinal sectional view taken therethrough'; Fig. 4 is a perspective view of the device in use in forcing a belt onto an overhead pulley revolving in clockwise direction, the uppermost follower-spring being under tension; Fig. 5 is a similar view showing the device after the throwing of the belt has been effected, thespring being in normal position; Fig. 6 is a similar view of the device in-use for replacing a belt upon an overhead pulley rotating in counterclockwise direction, the

, lowermost follower spring being under tension; and,-Fig. 7 is a similar view showing the device in userin replacing a belt upon a pulley located at'a lower level than the posi- 7 tion of the operator, the. said pulley being rotatable in clockwise direction.

Referring to the drawings, and in particular to Figs. 1, 2, and 3, the numeral 1 designates the body of the belt replacer, which is in the form of a rod rectangular in cross section, and which is constructed preferably of some light material such as wood, or the like. The length of this body depends upon the requirements of usage. When thedevice is intended for use in shops, wherein the belts and pulleys are suspended from high ceilings, the body 1 of each replacer is ofconsidera-ble length. The body 1 is provided at one end with a pointed engaging member 2, which is intended for a purpose to e described more fully hereinafter. A handle 3 p and the said body is provided adjacent each nron Patented Sept. 9,1913.

is secured to the opposite end of the body,

end with a slot 1 opening through the side faces 5 and 6 of the body. A grooved pulley wheel 7 is rotatably mounted in each slot 4 upon a transverse pintle. supporting member 9 is mounted upon the body 1, with its rectangular opening 10 receiving the said body. This member 9 is A slidable belt provided upon the side thereof correspondmg to the side face 5 of the body 1 witha lateral stub shaft 11 having a threaded recess 12 in its outer end. A belt engaging roller 13 provided with an external, peripheral groove 14, is provided with a'longitudinal opening 15 for the reception of the shaft 11, so that the said roller may be mounted rotatably thereon. The roller 13 is provided in its outer end facewith a circular. recess 16 adapted to receive a circular retainer plate 17, which latter is secured to the end of the shaft 11: by means of a threaded securing member 18 received within the shaft recess 12. Eye members 19 and 20 are formed on the upper and lower edges of the member 9 on the same side as the roller 13,

and helicaloperating springs 21 and 22 have their adjacent ends secured to the eye members19 and 20 respectively. The opposite ends of these springs are attached to flexible wardly along the side face 5 of the body 1 and through the adjacent slot 4:, passing around the pulley ,wheel 7 mounted therein. The cords 23 and 24: then extend inwardly cords 23 and 24:, each of which extends outalong the opposite side face 6 of the said body 1 to their points of attachment with the eye members25 and 26 respectively, provided upon theadjustable member. 27, which is slidably mounted upon the body 1 with its rectangular opening 28 receiving the same. I:

The member 27 is provided in the side portion thereof corresponding to the side face 6 of the body 1 with a threaded opening 29,

in which is adjustably mounted a threaded I bolt member 30 whose inner engaging end 31 is adapted to engage the said sidefaoe of the body 1. In order to prevent marring of the said side face 6 of the body, it is'necessary to provide a longitudinally extending metal strip 32 which is inlaid in the said faceand extends in the path of movement of the engaging end 31 ofthe bolt 30 for a suitable distance, depending uponthe extreme length of movement of the operating member 27. The bolt member 30 has its outer portion attached in suitable manner to the outer end face of the handle so as to close thecountersunk opening 33. A laterally promoting member 37 is provided in the body 1 ad-- jacent each slot 4, inwardly with respect thereto.

placer is thrust upwardly so that the roller 13 will be brought into engagement with the outer side edge of the belt 38 above the line shaft 39, the pointed engaging member 32 being inserted into the ceiling, or hanger plank 4L0 adjacent the pulley 41 upon which i the belt'is to be mounted. Then the operating handle 84 is grasped and pulled downwardly, so as to draw the member 27 in this direction and thus exert a pull upon the flexible cord 23. This will cause the belt to i I be elevated so that the upper portion thereof will become engaged with the upper portion of the pulley 41, and the uppermost spring 21 will be placed under tension. Then by a slight turn of the hand grasping. the handle 34, the member 27 may be secured against movement. By swinging the body of the device away from the shaft 39, while the pulley/i1 is rotating in the direction of the arrow, the belt 42 will be caused to climb onto the pulley, the follower spring 21 serving to aid in this operation by boosting the belt upwardly as the roller 13 is forced. outwardly. In Fig. 6 the operation is practically the same, except that the operating roller 13 is engaged with the belt:beneath the line'shaft 39, it being understood that it is necessary in this instance torotate the pulley 41 in counterclockwise direction, as necessitated probably by the kind of machinery connected to the line shaft. In Fig. 7 the device is shown positioned for use in replacing a belt upon a pulley disposed below the operators position, wherein the engaging member 2 is inserted in the floor,

rection, with the exception of the initial positioning or inclination of the replacer body itself, so as to bring the operating roller into engagement with the proper portion of the belt. After the operating roller under tension, the handle 34L is rotated so as to lock the member 27 upon the body 1. Rotation of the pulley in the proper direction will permit the spring to act in boosting thebelt as it climbs upon the pulley.

In Figs. d to 7 inclusive, I have shown the device put to various uses. In order to re- 1 place a belt upon an overhead pulley as shown particularly, in Figs4 and 5, the re- I From the foregoing description, taken in connection with the accompanying drawings, it will be seen that 'I have provided a belt replacer which maybe readily and efficiently operated by one person, two hands being required in the initial operation of the device, and the use of one h'an dalone after the operating member has been locked, The device is very simple in construction, and cannot readily get out of order, thus pre+ seating a structure which may be manufactured at a very. low cost, so as to bring the same within the reach of everyone who may have occasion to use such a device, thus presenting to the different mechanical trades a device which will prevent the danger and annoyance ordinarily incident with the replacing of belts upon pulleys, with especial reference to pulleys which must necessarily be rotated by power means while applying the belt. V
